4 START UP BEFORE CONTINUING, CHECK FOR OPEN DRAIN VALVES OR OTHER SOURCES OF FLOODING BEFORE STARTING UNIT. 1. Prime pump if necessary and adjust tank precharge to manufacturer s recommendation for intended pressure range. The factory WWDPC setting is 40 psi cut-in and 60 psi cut-out. 2. Turn on power and ensure WWDPC display illuminates, 88 will appear, then code revision number, then 00. Display will blank momentarily and the pump will start. If not, check installation. 3. The display will now read the current line pressure. 4. Allow the pump to reach the factory cut-off setting of 60 psi. IF THE PUMP CANNOT REACH THIS SETTING, DISCONNECT POWER AND SEE THE TROUBLESHOOTING SECTION ON PAGE Check for leaks and repair as necessary before proceeding. 6. Proceed to the ADJUSTMENT section. NOTE: During the first 30 seconds after start up, the pump can be made to operate manually by depressing the 5 arrow for 6 seconds. This is useful for priming jet pumps. DEVICE ADJUSTMENT (Entering Programming Mode) NOTE: Differential pressure cannot exceed 55 psi or be less than 10 psi. If display will not change, alter cut-in or cut-out to within 55 psi. 1. Press and hold. When LO appears, release. This will determine the pressure at which the pump activates. 2. When number appears, tap 5 or 6 to change cut-in setting. 3. Press again. When HI appears, tap 5 or 6 to change cut-out setting. This will determine the pressure at which the pump shuts off. NOTE: Depressing a third time will display the last Error Code in memory (see Error Code table in Troubleshooting section). If no errors have occurred, the display will show After approx. 10 seconds Pr will appear, indicating the settings are programmed. Display will then revert to line pressure. NOTE: The settings will now be stored until changed manually, even in the event of power failure. NOTE: If pump cannot reach cut-out setting within 5 minutes with no water running, lower the pressure settings to fall within the pump s pressure capabilities. NOTE: Pressing 5 6 together for 3 seconds will rotate the screen 180 degrees. This is useful if the control is mounted in an inverted position. OPERATION The WWDPC incorporates an accurate pressure sensing system capable of maintaining the set pressure range without the need for regular service or adjustment. The WWDPC controls the on/off cycling of the pump within the selected pressure range (see ADJUSTMENT section). The WWDPC also incorporates built-in diagnostic functions to protect the system and alert the user or installer to potential problems. If a fault is found, an error code will be displayed, indicating that service may be necessary. Error codes are listed in the TROUBLESHOOTING section. 4

6 GENERAL SAFETY INFORMATION WARNING: REVIEW ALL GENERAL SAFETY INFORMATION PRIOR TO INSTALLATION. READ CAREFULLY THE PRODUCT INSTALLATION, OPERATING AND MAINTENANCE INSTRUCTIONS. FAILURE TO FoLLOW THE INSTRUCTIONS AND WARNINGS IN THE MANUAL MAY RESULT IN SERIOUS OR FATAL INJURY AND/OR PROPERTY DAMAGE, AND WILL VOID THE PRODUCT WARRANTY. THIS PRODUCT MUST BE INSTALLED BY A QUALIFIED PROFESSIONAL. FOLLOW ALL APPLICABLE LOCAL AND STATE CODES AND REGULATIONS, IN THE ABSENCE OF SUCH CODES, FOLLOW THE CURRENT EDITIONS OF THE NATIONAL PLUMBING CODE AND NATIONAL ELECTRIC CODE, AS APPLICABLE. This product is used in conjunction with a system containing a tank under pressure, which may over time corrode, weaken and burst or explode, causing serious or fatal personal injury, leaking or flooding and/or property damage. To minimize risk, a licensed professional must install and periodically inspect and service the product and system. A drip pan connected to an adequate drain must be installed if leaking or flooding could cause property damage. Do not locate system in an area where leaking could cause property damage. EXPLOSION OR RUPTURE HAZARD. A relief valve must be installed to prevent system pressure in excess of local code requirement or maximum working pressure designated in the Product Manual, whichever is less. Do not expose system to freezing temperatures or temperatures in excess of 120 degrees. Failure to properly size the system or follow instructions in the Manual may result in excessive strain on the system and may lead to product failure, leakage, flooding and/ or property damage. This control is capable of running pumps to pressures that may exceed the limitations of system components. Never set the operating pressure higher than that of the safe system capacity. This control can be adjusted to a narrow pressure differential. This can cause the pump to cycle rapidly with an improperly sized tank, leading to pump damage. This may require a larger pressure tank than is normally used. ELECTROCUTION HAZARD. Must be installed by qualified professional. First disconnect all electrical power before attempting service. For your safety, the information in this Manual must be followed to minimize the risk of electric shock, property damage or personal injury. A water test must be taken before installation of any water treatment equipment. The water quality can significantly influence the life of your system. You should test for corrosive elements, acidity, total solids and other relevant contaminants, including chlorine and treat your water appropriately to insure satisfactory performance and prevent premature failure. Use only lead-free solder and flux for all sweat-solder connections, as required by state and federal codes. 6

7 DANGER! EXPLOSION HAZARD. When the well tank has been in service and a change to a higher pre-charge pressure is necessary due to a required change in the pressure switch setting, failure to follow instructions below can cause a rupture or explosion, possibly causing serious or fatal personal injury and/or property damage. Do not adjust or add pressure if there has been a loss of air. Do not adjust the pre-charge pressure if there is visible exterior corrosion. Do not adjust the pre-charge pressure if there has been a reduction of the pump cycle time or the pre-charge pressure compared to its initial setting. This is because reduction in pump cycle time can result from loss of tank air pressure which in turn can mean there may be internal corrosion and any re-pressurization or additional pressure could result in rupture or explosion. Do not install with components that are incompatible with the WWDPC. Note: inspect for shipping damage and notify freight carrier or store where purchased immediately if damage is present. To avoid risk of personal injury and property damage, if the product appears to be malfunctioning or shows signs of corrosion, call a qualified professional.
